It seems to me (maybe) that what is happening is that InterConnect is not closing the FTP connections after it FTPs a file, and after a while there are too many connections open. If I bounce the adapter, it works fine again for a period of time. I also delete the log files, but don't know if that has any relationship to this. Is there some parameter in the adapter.ini file I can set, or do I need to see a Unix sys admin about this???

This was addressed in a similar TAR: 4380173.994. Here is the solution I remember:

### Detailed Problem Statement: ###
When FTP adapter has run for some time (1 or 2 days) it keeps on failing with
error message:
Caused by: oracle.oai.agent.adapter.transport.TransportException: Unable to
enter passive mode. rc = 425 425 Can't open passive connection: Too many open files
at oracle.oai.agent.adapter.transport.basic.ftp.FTPAgent.getFileNames(FTPAgent.java:
253)

... 3 more

This error was already reported in tar 14948114.6. The solution back then was
to increase no of open files in server running the adapter. We have done that
but it does not seem to help (it might take some more time to run to this error
though).

POTENTIAL SOLUTION(S)
======================
Set the following adapter.ini parameters:
sender.keep_connections=false
receiver.keep_connections=false
